we want to give your science geek viewers an update what is going on. you are among our most favorite viewers by the way so here's an update. nasa rover curiosity that landed early last month is making pretty big progress. curiosity using the robotic arm to touch a martian rock. first time that happened according to scientists. a laser on the end of this arm we're looking at in this picture zapped the rock and analyzed its composition. and then the rover took off on its longest drive, so far, 140 feet, which might not sound like a lot but this is taking place on mars, folks. of course the big work still lies ahead. the rover slowly but surely making its way to the foothills of a giant mountain, mount sharp. about six miles from where the roof very is right now. there is belief there is evidence of water at the base of that mountain that water once existed there and perhaps that could mean life once existed there too. the rover could start making its way toward mount sharp by the end of the year. we'll keep you posted on the 2 1/2 billion dollar mission
